Filed Dec. 27, E969, er. No. "73,626 7 Eiaims. (El. 13'73l3) This invention relates generally to valves and is more particularly directed to a device capable of penetrating a line or tubing and useful as a valve for controlling the flow of fluid through the opening cut in the tubing.

A principal object of the present invention istoprovide a combination line penetrating valve device with a cutting needle which cuts an opening in the line or tubing and swages a seat thereon to control the flow of fluids therethrough.

Another object of the present invention is to provide a combination line penetrating valve device with a slide fastening member for securing the device to the line or tubingwith ease and without any danger of the slide member becoming loosened or inadvertently remove therefrom.

Another object of the present invention is to provide a combination line penetrating valve device having a minimum of parts, inexpensive in cost of manulacture, simple in operation and requiring no tools for the actuation of the valve.

A further object of the present invention is to provide a combination line penetrating valve device with a cutting needle which when first rotated makes a spiral cut in the wall of the tubing and then swages a seat on the wall of the tubing without severing the spirally cut material or affecting the eificiency of the valve to control the flow of fluid therethrough.

A still further object of the present invention is to provide a combination line penetrating valve device with an adapter to permit use of the device in connection with lines or tubing of various sizes.

A still further object of the present invention is to provide a combination line penetrating valve device which is rendered leakproof by virtue of the simplicity of the construction of the device and the effective use of a plurality of seals and valves in connection therewith.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

FIGURE 1 is a side elevational view of my line piercing valve.

FIGURE 2 is a front elevational view thereof.

FIGURE 3 is' a top plan view thereof.

FIGURE 4 is a cross sectional view taken along the line 44 of FIGURE 1.

FIGURE 5 is a similar view showing a line after hav ing been pierced with a valve in the open position.

7 FIGURE 6 is a similar view showing the piercing of a smaller line by the use of an adapter and with the valve shown in its closed position.

FIGURE 7 is a perspective view showing the manner by which my line piercing valve is mounted on the tubing or pipe line.

FIGURE 8' is a fragmentary side elevational view of FIGURE 9 is a cross sectional view taken along the line 99 of FIGURE 8.

FIGURE 10 is a cross sectional view of my valve supporting cap.

Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers to my line penetrating valve device consisting of a main body member 11 having a cylindrical shape for the purpose of convenience, although any other shape of the body member 11 would not diminish' the eificiency attained during the normal use of the device iii. The main body member 11 is slotted along its full length at its lower portion as at 12 with a wider rectangular slot 13 above and adjoining the slot 12 to form a pair of spaced apart shoulders 14 in the main body mem- -er ll.

Mounted on the main body member 11 and cast integrally therewith is an upwardly extending neck portion 15 threaded on its outer surface as at 16. A centrally disposed bore 1.? extends along the neck portion 15 and communicates with an approximately hemispherical shaped chamber 18 the lower portion of which opens into the slot 13. At the top portion of the chamber 18 there is a peripherally disposed ridge 19 extending in a downwardly position. Mounted in the chamber 18 is a rubber or plastic seal 26 conformed to fit in the chamber 18 and engaging the ridge portion 19. The seal 20 is provided with a conical bore 21 anda cylindrically shaped bottom wall 22 for engaging the outside surface of a pipe or tubing 23 as is explained in greater detail hereinafter.

Means are provided for maintaining the pipe or tubing 23 secured in position in the main body member 11 comprising a slide member 25 which fits snugly in the slotted portion 12 with arm portions 26 fitting snugly in the slotted portion 13 and abutting against the shoulders 14. The slide member 25 is provided with a longitudinally disposed semi-cylindrical slot or groove 27 at its upper portion for receiving and supporting the tubing 23. In order to permit the slide member 25 to be readily received by the slots 12 and 13 in the main body member 11 the shoulders 14 as well as the ends of the arm portions 26 of the slide member 25 are provided with inclined portions 28 and 29 respectively at each end thereof. A boss 30 is mounted on the lower surface and at one side of the main body member '11 while a second similar boss 31 is mounted on the lower surface of the slide member 25.

ing centrally and. upwardly of the cap 34 is a neck portion 37 gwhose outside surface is threaded as at 38 for receiving a coupling of a pipe line (not shown) when connecting the penetrating valve device it to a source of'gas,

etc. The upper surface 39 which is tapered as shown forms a gastight seal between the. connecting pipe and the device Iii). y

Secured to the cap 34- is a cutting needle 46 whose upper shank portion $2 is force-fitted into a centrally disposed bore all in the cap 34 to thereby become integral therewith. The needle 4a) is provided with an axially disposed fluid passageway dfi which extends from the top portion of the needle 40 to a position adjacent its cutting end 44- where the passageway 43cornmunicates with a A tool 32 pro vided with an elongated slot 33 is used to slide the slide.
